Emergency crews are searching for a missing inner tuber who disappeared Monday evening while floating down the Puyallup River near Sumner.

Pierce County sheriff's officials said the missing 25-year-old man had been with several buddies floating down the river. But when they reached their destination at about 7:30 p.m. Monday, they realized he was missing.

The group searched themselves for a while, but could not find him.

Finally, at about midnight, they notified authorities, who launched a more intense search. The missing man's friends told deputies they believed he was high on cough medicine.

Search crews worked into the night, with bright lights on the water and walking the shore calling the name of the man - with no luck.

The search was resumed Tuesday morning, beginning near 80th Street East and Highway 162.
